To altwhomit may concern:

Be 1t known that 1, Hanan H. Gon'rnn, a citizen of the United States, residing at San Francisco, in the county of San Fran- 5; Fig. 3 is cisco and State of California, have invented new and useful Improvements in High- Pressure Nozzles, of which the following is a specification.

The present invention relates to proved high pressure water nozzle, for use infire boats, water towers, and fire extinguishing apparatus of all kinds, also for hydraulic mining, or wherever a high pres sure nozzle is used.

The objects of the provide a nozzle by invention are; first, to which all the particles of the jet of water are directedoutward with substantially the same velocity, and without any lateral or rotary motion, the effect being to produce a stream which will not spread, but will be maintained of a uniform diameter, like a solid bar, for a much greater length than has been obtained by nozzles heretofore provided; second, to provide a nozzle so constructed internally as to prevent eddies or churning in the water, and to avoid friction of the water, as much as possible especially at the point of juncture between parts of the nozzle; third, to provide a nozzle so constructed as to avoid forces pro.- duced by the impact of the water against the interior surfaces of the movable part of the nozzle tending to turn the same; fourth, to provide a nozzle, the movable part of which is at [all times easily moved upon its support; fifth, to provide a nozzle, which can be very quickly locked in any desired position; sixth, wherein the means for producing uniformity in the'velocity and direction of is a broken side elevation of the apparatus;

2 is a section on the line 2-2 of Fig. a detail sectional view of the outer ball section'removed; Fig. 4 is an enlarged sectional'view through the lever for vertically operating the nozzle; Fig. 5 is an enlarged verticalsection through the lower portion of the apparatus; Fig. 6 is a simi- Fig.

la-r view through the upper or terminal por-.

tion of the nozzle; Fig. 7 is an end view of an imthe stationary and the movable flow can be readily removed and replaced when desired; sevent'h, to providethe centralizer; Fig. 8 is a section above the ball joint, certain parts being'broken away.

Referring to the drawing, 1 indicates a tubular lower portion of a nozzle'which is adapted to be secured, either by being screwed, or by means off a flange, as shown at 2, to the end of apipe or to an opening from a receptacle for water under pressure. Within said tube is inserted a sleeve 3, upon the lower end of which are screwed rings 4, 5, the upper ring 4 being formed with a runway for balls 6 which also travel within an annular rounded corner 7 formed in the lower portion of the tube 1. These balls receive the upward thrust of the nozzle against the tube 1 while avoiding friction from said thrust. Screwed into an enlarged upper end of said tube by a suitable device applied to sockets 8 therein, is a ring 9, between which and said tube is an angular packing ring 10, the inner surface of which bears against the outer surface of the sleeve 3, and prevents escape of water therefrom. Secured byscrews 11 to a flange 12 formed on said tube 3 is a ring 13 formed with a.

plurality, three being here shown, of recesses 14, in which are contained rollers 15 on vertical screws 16 screwed into said ring and forming journalpins for said rollers. Said rollers bear against the upper enlarged portion of-the tube 1, and take the back thrust of the stream of the nozzle, while avoiding friction, thus enabling the sleeve 3 to be turned easily within the tube .1. It can be clamped in any desired position therein by means of a shoe 17 which is screwed against the enlarged portion of the tube 1 by a screw 18. Above said flanged portion of the tube 1 there is formed transversely in the wall of the sleeve 3 an aperture 19,'into which can be inserted a bar constituting a turning lever for the purpose of turnin the nozzle horizontally by hand, this being effected with comparative ease owing to the aforesaid arrangement of the balls 6. Said sleeve has at the top a cup-shaped enlargement 20 extending from the lower portion of the sleeve in a general direction of about 30 degrees, and has a circular end threaded on the outside, as shown at 21, upon which is screwed a fulcrum ring 22, in which are formed the fulcrums or crum pins 24 whichenter sockets 25 formed in the wall of the ball or. spherical shaped lower portion 26 of the nozzle proper 27.

Said circular end is formed with a recess 28 bearings 23 for ful I to receive a packing 29 formcdof a strip of leather folded longitudinally, one side there s the bearing ring 22, the 'ball section 'of the nozzle can be readily removed from the of g ging the outer surface of the ball 26,

and the other engaging the inner surface of said recess 28. Between the twosides of said strip is interposed a coiled spring 30, being ofbronze the coil being' bent into a circle and inserted between the two sides of said strip, tending to keep said sides as far apart as possible. Said packing 29 isbe low, or on the near, side of, the axis upon which said ballturns, sothat, by unscrewing socket section thereof. It is desirable from this class of devices to eliminate as much as possible any churning action in the water during its course from its source of supply to the end of the nozzle since such churning or eddying causes loss of power by friction. To avoid this action, there are cast within the lower end of the sleeve 3 bars 32 crossing each other at right angles, each bar ,being comparatively thin in proportion to its.

height and having sharp upper and lower edges, so as to prevent any lateral or eddying motion of, the liquid passing through. To attain the same object there are also formed in the inner surface of the enlarged or flaring upper portion 20 of the sleeve two opposite inwardly extending longitudi nal ribs 33, 34. These ribs also reduce the lateralmotion of the water and prevent eddies or churning.

Within the ball portion of the nozzle an inner Wall 36, substantially cylindrical in form is screwed, as shown at 37, into a cylindrical flange 38, formed integral with the outer spherical wall 26. Also screwed into saidfiange 38 and abutting against the end 'of said inner wall 36-, is the lower end of a nozzle tube 39, having a flange 40 which abuts against the spherical wall 26 of the ball portion of the nozzle. {Extending from said nozzle tube 39 are a pa'irof lugs 41, to

which is pivoted an end of. a link 42, the.

other end of which is connected to the forked end of an arm'ofabellcrank lever 43, pivotedon a bolt 44 1passed through two lugs 45 castupo'n the wa l of the cup-shaped socket section 20 of the nozzle, another arm 46 of said bell crank leverbeing formed with a socket 47 to receive the end of a lever bar 48, by which said bell crank lever can be turned to turn the ball section of the nozzle.

in its socket lon its journalpins.

Theinner cylindrical wall of the ball por tion is formed in itsvinner surface with a cylindrical recess 50 having a shoulder 51 in which recess is received the cylindrical wall 52 of anequalizer 53, formedwith an inner c lindrical wall 54 and radial walls 55,

56, which divide the interior of said equal izer into compartments .57 nine being here shown, all of these compartments being prismatic in form and of substantially the same area.

. When a stream ofwater is flowing through a conduit at a high velocity, the velocity of the stream in the center will be greater than that at the circumference in contact with the walls of the conduit. Now if a stream of waterissues from a nozzle in which the outer portions are projected at a less velocity than the central portion,lthe eifect is, that the central portion, issuing with a greater velocity than the outer portion, imparts to said outer portionsa lateral motion causing the stream of water to spread. It. is there: fore very desirable toobtain in such a stream a velocity in all of the particles as uniform as possible. This result is efiiected by the 'abovedescribed equalizer, since it-sets up,

a slight retardation of the stream of water dividing the stream into sections, each of which may be considered as a separate jet, flowing through a chamber of the equalizer, their velocities being rendered uniform by reason of the. fact that the equalizer permits the' water to escape equally through each section thereof.

portions are retarded, by the friction against the wall of said nozzletube, while the central portion retains its high velocity. It is 1 Upon the upper portion of the nozzle tube desirable to permit onlythis central portion, 7

having a high velocity, to emerge from the nozzle tip. It is to efiect this purpose that the centralizer is provided. This centralizer water to flow through the central wall with practically undimimshed velocity, the outer portion of said stream forming a liquid wall for the central portion, and being held, back Within the nozzle tip by the pressure of said central portion of the stream, so that the outer portion of the stream practically never escapes, and the only portion which emerges 'isthe central part which has passed through a central wall of the centralizer.

An important-f feature of this invention resides in the-i form of the ball and socket. In priorforms of nozzles having ball and socket joints, as, for instance, that shown in my United States Patent No. 557,799, the

nozzle tube, carrying the nozzletip, was con nected to the socket, and the ball was connected to the stationary. section. The result was that the stream of water passing-through i permits the central part of the stream of great pressure pressure of ,the

, bolt 44, the

to be quickly worn the inner wall of the ball section of the nozzle impin ed with great force against the inner sur ace of the socket carrying the nozzle, tending to turn it upon the ball, and this tendency had to be resisted by powerful means, as, for instance, a screw working in a nut attached to the socket. Owing to the of the stream of water iminging against said socket it required great orce to turn the same when in operat on. In my present form of ball and socket oint, whatever be the position of the ball joint, the pressure thereon is balanced, so that there is no difliculty in turning the same within the socket. This allows of a quick action, because the force required to move -1t does not have to be increased by mechanical means, said increaseof force involving a sacrifice of speed. v

The ball section can be locked in any desired position by means of a lever 7 0 having a'forked end pivoted upon the end of the eccentric-ally to the bolt, so that upon turning the lever in line with the bolt, the bell crank lever 43 is fixedly clamped between the two lugs 45, these lugs being made of considerable size so as to provide a large frictional surface to grlp the bell crank lever.

It will be observed that the edge of extension 20, where it contacts with the spherical portion of the nozzle, is normal to said spherical portion, and said extension curves gradually inward from said edge to the sleeve.

, It is important that the parts 64: and 51 be readily removable, because they are apt bysand gravel and the like forced through the nozzle by the high water, and, in fact, large pieces of stone might become lodged in said parts and obstruct the flow of the water.
